[0045] The refrigeration container 200 is used for preparing cold water or ice cubes.

[0046] In the scheme, on the one hand, the filter device 100 is used to remove impurities in the water, so as to provide pure, high-quality and odorless water for the refrigeration container 200 to prepare cold water or ice cubes, improve the quality and taste of the cold water or ice cubes, and improve the user experience. On the other hand, the waste water generated by flushing the filter device 100 is used as a heat exchange medium, the waste water is introduced into the heat exchange module, the waste water absorbs the heat absorbed by the heat exchange module from the refrigeration container 200, and the heat exchange cycle of the refrigeration device is completed.

[0047] As an implementable way, the heat exchange module comprises an evaporator 210, a compressor 220, a condenser 230 and a heat exchange water tank 240;

[0048] The evaporator 210, the compressor 220 and the condenser 230 are connected in sequence to form a refrigeration circuit;

[0049] The condenser 230 is connected with the heat exchange water tank 240, and the water inlet of the heat exchange water tank 240 is connected with the waste water outlet of the filter device 100;

[0050] The heat exchange water tank 240 is used for absorbing heat of the condenser 230 with waste water.

[0051] In the present scheme, the evaporator 210 covers part of the outer surface of the refrigeration container 200 to absorb the heat of the refrigeration container 200, form a refrigeration environment in the refrigeration container 200, and the compressor 220 inhales low-temperature and low-pressure gaseous refrigerant from the evaporator 210, compresses the low-temperature and low-pressure gaseous refrigerant into high-temperature and high-pressure gaseous refrigerant, which is discharged from the compressor 220 and enters the condenser inlet 231. After the high-temperature and high-pressure gaseous refrigerant enters the condenser 230, it is gradually cooled and condensed into a liquid state by heat exchange with the waste water in the heat exchange water tank 240. The inlet water of the heat exchange water tank 240 is introduced into the filtered waste water from the filtering device 100, and the waste water is used as a heat exchange medium to exchange heat with the condenser 230 and absorb the heat released during the condensation process. The waste water after heat exchange is discharged from the outlet water of the heat exchange water tank 242, and then the liquid refrigerant condensed in the condenser 230 flows from the condenser outlet 232 to the evaporator 210 and exchanges heat with the refrigeration container 200.

[0054] As an implementable way, the heat exchange water tank 240 further includes a water supplement inlet and a water discharge outlet.

[0055] In the present scheme, according to the temperature of the working environment of the refrigeration device and the refrigeration demand of the user, the water supplement inlet of the heat exchange water tank 240 is used to increase the heat exchange medium for cooling the condenser 230, improve the refrigeration efficiency and performance of the refrigeration device; at the same time, the heat exchange medium after absorbing the heat of the condenser 230 is discharged through the water discharge outlet, the flow of the heat exchange medium is increased, and the refrigeration efficiency and performance of the refrigeration device are further improved.

[0056] As an implementable way, the refrigeration container 200 is provided with a water level sensor, and the water level sensor is arranged at the top of the refrigeration container 200.

[0057] In the present scheme, the water level sensor is installed at the top of the refrigeration container 200, which can simplify the installation process, reduce the installation time and cost, and facilitate the maintenance and replacement of the sensor. In one embodiment, the water level sensor is an optical water level sensor or a capacitive water level sensor to achieve non-contact measurement, avoid direct contact between the sensor and the liquid in the refrigeration container 200, thereby reducing the wear and contamination of the sensor, and improving the stability and reliability of the measurement

[0058] As an implementable way, the filter device 100 includes a pretreatment filter core 110 and a reverse osmosis filter core 120.

[0059] The water inlet of the filter device 100 flows through the pretreatment filter core 110 and the reverse osmosis filter core 120 in turn.

[0060] In the present scheme, by integrating the pretreatment filter core 110 and the reverse osmosis filter core 120 as the filter device 100, efficient water quality purification is achieved, the equipment is protected, the water quality safety is improved, the taste and odor are improved, the cost is saved, and the operation is simple.

[0061] As an implementable way, the pretreatment filter core 110 is a PP cotton filter core, a granular activated carbon filter core, and / or an ultrafiltration membrane filter core.

[0062] In the present scheme, the PP cotton filter core can effectively remove large particles in water, such as silt, rust, suspended solids, etc.; the granular activated carbon filter core can remove residual chlorine, odors, colors, and part of organic matter in water; and the ultrafiltration membrane filter core can efficiently remove suspended solids, bacteria, viruses, and macromolecular organic matter in water. According to the water quality requirements of the filter device 100, various pretreatment filter core 110 schemes can be used to improve the stability and precision of the filtration.

[0063] As an implementable way, the reverse osmosis filter core 120 is an RO reverse osmosis membrane filter core.

[0064] In the present scheme, by using the RO reverse osmosis membrane filter core, all dissolved solids and small molecular organic matter in water can be removed, and harmful substances such as heavy metals (e.g., lead, mercury, cadmium, etc.), pesticide residues, bacteria, viruses, etc. can be effectively removed, thereby improving the water quality and taste of the output of the filter device 100.

[0065] As an implementable way, a booster pump 130 is further provided between the pretreatment filter core 110 and the reverse osmosis filter core 120.

[0066] The booster pump 130 is used to provide water pressure.

[0067] In the present scheme, the booster pump 130 ensures the stability of the water flow and the uniformity of the pressure, thereby improving the efficiency and stability of the entire filter device 100.
